Customizing Axes
This bar chart shows the population of the top 10 most populous countries using 2018 estimates from the United Nations World Population Prospects. It highlights the customization of D3 axes, including a left axis with removed tick marks, a bottom axis with compact billion/million formatting, and custom axis labels. The visualization uses d3.csv to load data, d3.scaleLinear and d3.scaleBand for scales, and d3.axisLeft and d3.axisBottom for axes, all rendered as SVG.
